SIDE BEARING FOR CARS.

Specification of Letters Patent.

Patented Dec..10, 1907.

Application led June 3. 1907. Serial No. 377.059.

To @ZZ whom it 'may concern? j Ile it known that I, JonN G. BARBER, a citizen of the United States, residing 'at Ohicago, in the county of' Oook and State of Illinois,. have invented certain newand useful Improvements in Side Bearings for Cars and I do hereby' declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to side bearings for cars and has for its object to improve the same in the several particulars hereinsomewhat on the distance that the side bearing is located from the center bearing, and

this varies in different ears. Also, in different cars4 of the same type, the distance-between the truck bolster or side bearing suplport of the truck and the overlying body olster of the car will vary. Furthermore, under rough service and continued use, there is a tendency .tor the truck bolster and thev bolster to Work closer together. All ot t ese conditions makedesirable a vertically adjustable side bearing. Hence, as the princi al feature of mypresent invention, I provi e a novel construction whereby the side bearing is made vertically adjustable.

In the accompanying drawings which illustrate the invention, .like characters indicate likeparts throughout the Several'views.

Referring to the dravings, Figure 1 is a plan view of one of the improved side bearings, Fig. 2 is a bottom plan view of the same. Fig. 3 is a vertical section taken on the line x3 of Fig. 1; and Fig. 4 is a side elevation of the im iroved side bearing, showing also ortions oi a truck bolster. and a car body bol ster between the ends of which the side bearings are applied.

The im proved side bearing, in its preferre form, comprises three rollers 1, a divided or two-part roller supporting bracket 2 in which the trunnions of said rollers are journaled, a base member 3, which, as shown, is bolted or otherwise rigidly secured to the underlying -end of the truck bolster 4, and an intermediportion ofthe intermediate member or adjusting sleeve 5, andA the two parts thereof are divided on a line that extends transversely of the intermediate portions of the rollers l, so that the seats for the trunnions of the said rollers are ada ted to be moved apart and toward each ot er for the purpose o removal or application to said trunions. Preferably, the-two sections o f the said bearing bracket 2 are rigidly secured togetherby rivets 6 assed thr'ough depending flanges 2b' of said racket, and the said flanges 2b "at their ends are bifurcated or notched so that they engage vertical ribs or guide lugs -7 formed on the interior of the hub 3a. In this Vso way, the roller bearing member 2 while free for vertical adjustmentsunder the action of the adjusting sleeve '5,is' held against rotation and, hence, the rollers 1 are always held in pro er Working positions for engagement with t e roller bearing plate 8 of the ear body bolster .9.

In Fig. 3, the roller bearing bracket- 2 is shown in its lowermost position7 in which position its flange 2a bears against the top of the hub 3a as well as against the top of the adjusting sleeve 5. l

In Fig. 4, the adjusting sleeve '5 is shown l as screwed upwardon the hub 3EL so as to move the bearing bracket 2 and its rollers-1 higher up than shown in Fig. 3, and in this i vadjustment of-the parts the flange 2EL of said bracket 2 rests only upon the top of the said adjusting sleeve. ImmediatelyA underlying the flange 2a ofthe bearing bracket 2, the ad-y justing sleeve 5` is provided withl an out-- wardly extended Harige 5a. Both of these flanges 2aL andl 5a are provided with perforations that are-adapted to be moved into registration in diierent rotary adjustments of the said sleeve 5 with respect to said bracket 2, and through which split keys 10 or other suitable lock devices are adapted to be passed to lock the sleeve 5 a ainst rotation and, hence, in any vertical a justment in which it may be set.

What I claim is:

l. A vertically adjustable side bearing for cars com rising a base member, a vertically adjustab e bearing bracket held against rotation in res ect to said base member, rollers on said brac et, an intermediate rotary ad- 'nsting member operative 'on said 'base memer and bearing bracket to vertically adjust said bracket and its rollers, and means for locking said adjusting member against rota ltion, substantially as described.

externally threaded hub portion, an ad ing sleeve 2. Avertically adjustable side bearing for cars, comprising a base member, a rotary ad justing member having threaded engagement with said base member, sup sai 4Nadjusting member, but hel tion with respect to said base a bearing bracket against rotamember, and

bearing rollers journaled 1n said bearing bracket, substantially as described.

3. A vertically adjustable side bearinfgfor cars, comprising a base member having an justsurrounding and yhaving threaded engagement with said threaded hub, a roller orted by, and vertically ad'ustable with an 'adjusting sleeve 5 working with threaded engagement on said hub, a two-part roller bearing bracket 2 havin a projecting flange 2a resting u on .said s eeve 5 and havin iianges 2b, t ie ends of which embrace sai guide lugs 7, thereby holding the said bracket 2 against rotation but permitting vertical movement thereof, bearing rollers mounted on said bearing bracket, and means for locking said adjusting sleeve 5 against rotation with respect to said bearing bracket, substan tially as described.'

In testimony whereof I aiiix my signature in presence of two Witnesses.

JOHN' C. BARBER.
